The SunglassRevivers standard

compatible lenses, built like they belong there

We obsess over one thing: that your revived sunglasses look, fit and perform like the day you bought them. Every lens leaves our workshop only when we would wear it ourselves.

01

Optical-grade clarity

Distortion-free lenses cut from hard-coated polycarbonate (CR39 for clear options) — crisp edges, true colours, zero eye strain.

02

Cut to your exact model

Precision-machined to the curve and bevel of this frame model, so they click in at home and sit flush — no gaps, no rattle.

03

100% UV400, every colour

Full UVA/UVB protection is built into the material itself — and polarized options cut reflected glare from roads, water and snow.

04

Backed for 3 full years

Quality-checked before shipping and covered by our 3-year warranty against manufacturing defects — at a fraction of the price of a new pair.

Independently manufactured compatible parts — not products of the frame brands. That independence is what lets us focus everything on quality and price.

DETAILS

about this product

The Ray-Ban RB4165 Justin ships in three eye sizes — 51mm, 54mm, and 55mm — so check the size stamped on the arm you're replacing before ordering, since the three don't interchange and aren't sold as one universal cut. This aftermarket pair is built for the model's square plastic front and 145mm plastic arms, with a full run of tint options: solid neutrals, three gradient shades, eight mirror finishes, a photochromic grey, and a clear AR lens for indoor or prescription use.

Square frames like the Justin tend to suit rounder faces, since the straight top and bottom lines add structure a curved lens wouldn't. If the frame itself still sits straight and only the lenses are scratched or scuffed, swapping the lens pair is the cheaper fix before you consider replacing the whole pair of sunglasses, and with three sizes on offer it's worth measuring twice rather than guessing which one your Justin takes.

Frequently asked questions

Will these lenses actually fit my exact Ray-Ban or Oakley frame?

These lenses are cut to the 51mm eye size and Square shape of the Ray-Ban 4165, so they seat into your existing frame's groove without trimming, heating, or any modification on your part.

Do replacement lenses block UV rays as well as the ones they're replacing?

Every lens we sell, including each option among the over 15 lens colours, including mirrored and polarized options, blocks 100% of UVA and UVB radiation, so changing the color or finish on your 4165 never means sacrificing sun protection.

What's the warranty if a lens pops out or discolors after a few months?

All lenses are independently made and carry a 3-year warranty against manufacturing defects — if a 51mm lens fails to seat correctly or the coating degrades on its own rather than from an impact, we'll replace it free.

Are these genuine Ray-Ban or Oakley lenses?

No — these are aftermarket lenses, independently made to match the 51mm dimensions of the Ray-Ban 4165. They aren't produced or endorsed by Ray-Ban; they're engineered purely to fit that frame correctly.
